.fication, reference being had therein to the accompanying drawings. t

The invention relates to new a-nd useful improvements in a machine for making glassarticles.

The invention comprlses a machine 1n which a mold 1s `moved lnto operative relation to the exit from a tank or pot containing '.nolten glass so that. the glass therein may .fall or iow from the tank and be caused to fill or supply the necessary glass `to the mold for making a blowing blank, also such mechanism as will shape the charge of glass into al blowing blank and subsequently expand it into the article to be made.

The invention further consists in such a machine in which the inlet or fill opening of the mold is'uppermost, the mold being in an inverted position comblned with mechanism for reversing the mold to its upright position, and expanding the blank after it has been thus turned.

The invention further consists in the peculiarconstruction of the pot or tank by which theglass may be caused to fiow at the desired speed to the molds and further in the construction, arrangement and combination of the various parts as more fully hereinafter described, and particularly pointed out in the claims.

In the drawings Figure 1 is a perspective view of one arm of the machine, of which there :tre to be a multiple showing'the mold justcoming into position to be lled. The tank'or ot is shown in section as is also the standar which supports and carries the mold arms. Some of the parts are broken away to better' illustrate the connections. Fig. 2 is a vertical central section on line -m Fig. l0 through the blowing blank mold, neck mold and the blowing and suction head showing the same in position for filling. Fig. 3 is a section through the upper end' ofthe same mold showing the same moving away from the filling position and cutting off the glass. Fig. 4 is a-perspective view of the operating parts at the end of one ofthe mold arms showing the blowing mold inclosed about'the blank ready for blowing, and one section of the blank mold in its open position, the support for the other section being broken away soas to ive a proper view of the operating parts. Fig. 5 is a section partly in elevation, of the blank suspended open position opposite the blowing mold. in pos1tion ready for the blowing operation which position is shown in Fig. 4, the sections of the blank mold being shown in their open position opposite the blowing mold. Fig. 6 is a similar section showing the article expanded in the blowing mold. Fig. 7 is a sectional elevation of the parts shown in Figs. 5 and 6, the neck mold beingopen, the article finished and the body mold ready to lower and open to deliver the finished article.

Fig. 8 is an elevation of the melting tank, the

tilting pot or-tank into which the continuous tank discharges and showing a diagram elevation of the machine to illustrate the relation of the melting and liowing tanks, and the machine in general view. Fig. 9 is a plan view of the star wheel. and the index wheel by means of which the mold arms are caused to7 intermittently travel or move. Fig. 10 is a section partly in elevation of one of the mold arms, showing the air chamber, cams, and the mechanism for operating the same.

1 represents the base which supports the operating parts of the machine.

2 is a short tubular. standard supported on the base within which is the rotating tubular post or standard 3, supported upon the base 1.

On the outside of the. tubular post .3- is" secured a star wheel 4L shown in. Figs. 1 and 9 adapted to be actuated intermittently and .locked between operations by means of the index wheel 5 which engages in the curved bearings 6 of the star wheel to lockI the standard in position and having the rollerl i wrists 7 adapted to engage the slots 8 to give the star wheel and the standard 3 a partial rotary movement. The index wheel 5' is provided with a worm wheel 9 with which a worm l0 ongthe shaft 11 engages, this shaft being driven continuously from any suitable source of power.

It is my purpose to have a series of mold arms'carried by'thestandard 3 but inasmuch' as they are all alike I have illustrated and will describe but one, it being understood that the others have simply a duplicate mechanism thereon, and that any desired number could be supported upon the standard 3.

` 12 is a gear wheel having a tubular hub 13 which engages in a bearing 14 near the upper portion of the standard 3. Secured to the gear wheel 12 at 15 is the mold arm 16. This mold arm is stiffened and supported by the brace or bracket 17 which at its inner end is likewise secured to the gear wheel 12. Between the bracket 17 and the arm 16 is a space which I utilize for the cams for operating the various parts as will be hereinafter described.

At the outer end of the arm 16 (Figs. 1, 4 and 10) I carry the suction and blow head 18. Above the blow and suction head are the neck mold sections 19 which are supported respectively upon the outer end of the levers 20 pivoted in the brackets 21, the inner end of these levers having connected to them the links 22 which are pivoted together and to an actuating rod 23 which at its inner end has a roller wrist 24 engaging a camway 25 in the cam wheel 26 on the shaft 27. The levers 20 and 22 make a toggle which is actuated by the vrod 23 to open and close the neck mold sections. They are shown in closed position in Figs. 1, 2, 4, 5, 6,

and 10 and open position in Fig. 7.

Above the neck ring sections are the body blank sections 28 which aresupported on the outer ends respectively of the levers 29 pivoted in the bracket 2l, and having the links 30 which are pivoted to the ends of the levers and to each other, and are connected by the rod 31. At the inner end of the rod 31 is a roller wrist 32 engaging a camway 33 on the upper face of the cam wheel 26 on the shaft 27. The body blank sections will be opened and closed by this mechanism at the desired points in the operation of the machines, the cams and the drive mechanism therefor being. properly timed as will be hereinafter explained.

The suction and blowing head shown in Figs. 2, 5 6 and 7 has the central partition a which divides the head into two chambers and c the chamber c being in efect a cylinder in which is the piston d upon which .is the core plunger or pin e, the function of which is to form the indentation or the initial blow opening in the glass blank through which it may be blown. This pin projects through the flange hat the upper end of the suction and blowing head and slightly into the neck mold. The flange h is provided with an annular flange z' with whlch a corresponding recess in the sections of the neck mold engage as shown in Figs. 2 and 7. 7c is a gland to hold the packing around the pin e at the point where 1t passes through the partition a. Z is a spring between the gland and the piston d acting to normally hold the piston away from the gland and to withdraw the pin out of op,-`

erative position. The piston d is operated by air under pressure admitted into the end of the cylinder c throughthe pipe m. This pipe m leads to the hollow casing o shown in Fig. 10, and which is connected by means of a nipple p to which is attached a branch of a iexible pipe g more fully hereinafter described which leads to the interior of the hollow standard 3 where it is connected into a chamber 7' in the casing 1" at the upper end of the hollow post as shown in Fig. 1. This casing is provided with'air under pressure from the supply pipe s which connects to a ring s on the outside of the casing 7". This ring has a sliding engagement ywith the casing 1 so that the casing may turn within the ring while the aiil connection and the ring remain stationary. u is a valve controlling the exit lfrom the casing 0 into the pipe m. This Valve is on a stem u which has a roller wrist u engaging the camway in the cam wheel v on the shaft 27 the cam being so constructed as to open the valve at the proper moment, and to maintain it open when air under pressure is desired beneath the piston d to raise it and the pin e into the position shown in Fig. 2. The casing o is connected with the chamber b by means of a pipe c which connects into the port o in the mold head for thel purpose at the desired point of admitting air under pressure into the chamber I) for blowing the article to form when the parts are in the position shown in Figs. 5 and 6. This air connection from the casing o to the chamberb is controlled by valve w the stem of which is actuated by a camway in the cam on the shaft 27 1 and 10). The upper part of the casing 0 is separated from the lower portion by a partition A and above the partition is the vacuum chamber A. The chamber A is connected to the chamber b by a pipe B which connects to the port C in the mold head, and this vacuum connection is controlled by the valve C which in turn is actuated by a camway in thecam D on the shaft 27 as shown in Fig. 10 to open and close the vacuum connection at the desired time. The chamber A is connected with the vacuum chamber H formed below the chamber 1' in the top of the standard 3, by a flexible pipe H', which I have shown broken` away. The chamber H is connected .to the exhaust pipe J by means of a pipe K extending through the chamber 1". The exhaust pipe J is journaled in the casing 1" so that the casing'may turn about the ipe J while the pipe remains stationary. The end of the core or pin e which projects through the end of the suction and blowing head is slightly smaller than the openin Vthrough that head so as to make a passage leavin a narrow annular port E between the nec municate with the annular groove F -in the upper end ofthe neckmold which annular passage communicates with the vertical grooves G (Fig. 6) in the meetmg faces of the sections of the blank mold for the purpose of taking up anyleak of air which mi ht otherwise pass through these joints during the time thatl the vacuum 1s on.'

The body blank mold 1s provided at its free end with the lateral flanges 35 the flange upon one side being slight y longer than that upon the other side as shown in Fig. 2, and these fianges are beveled at thelr ends 4as shown at 36. These flanges abut at their outer ends with the ends of the ring sections 37. These ring sections'extend between the mold arms and are carried on a rotating standard 3 by means of the arms (Figs. 1 and 10') which are secured at their outer ends to the under side of the ring sections,

Aand' at their inner ends are secured to the brackets 39 which in turn are secured to the outer face of the standard 3 as plainly shown in Figs. 1 and 10. These brackets 39, I have shown in pairs near each mold arm, and they carry at their outer ends the frame 40 in which the blowing mold sections 41 are supported. I will describe the construction of the blowing molds and thelr operation later on; The ring sections 37 and the flanges 35 on the upper end of the body blank mold form in effect a continuous ring section or plate, which in the rotation of the standard 3 travels beneath the cup 42 supported on a' standard 43. The bottom of this cup isformed by the vring sections 37 and the flanges-35 during the traveling movement of the standard 3.

44 is a tank or pot adapted to'contain molten glass which may be supphed thereto in any suitable manner `but preferably is continuously supplied thereto from a continuous melting tank 45 which is shown in' cup 42 so that when the pot is tilted to cause the glass to flow therefrom the flowing glass will fall directly into the cup 42 and rest upon the ring 37 during the traveling movement thereof,

. In the periods of rest or stoppage of the standard 3 the body blank mold 28 will be stopped with its opening uppermost and directly in line with the opening through the cup 42 as shown in Fig. 2 so that the glass fiowing from the tank, and so much of the glass as may have accumulated on the ring sections during thev'traveling movement between molds will fall into thel body blank mold as shown in Fig. 2. It is intended 'that the fiow of glass from the tank 44 will be regulated by the shaft 50 so that during the stopping period ofthe blank mold sufficient glass will flow from' the tank into the mold to fill the same. As soon as the interval of rest ceases and the machine starts to bring another mold into operative relation to the flowing glass, the upper end of the blank mold will act to sever the glass fiowing fronrthe pot from that which is in the blank mold as shown in Fig. 3. At the time that the'blank mold reaches the stopping. point beneath the flowing glass as showin inl Fig. 2 the valve C is opened by the'cam D and the air is drawn out of thel chamber b in the suction head through the port C and also from the blank mold through the port or passage E and the port E" and the glass falling into the 4cavity of the blank mold will be forced therein by the atmos' p'heric pressure above so as to fill the mold cavity and give shape to the blank as shown in Fig. 2. During the neXt movement of the standard 3 after the blank mold is filled as shown in Fig. 2, tlie glass is cut off as previously described and as shown inFig.` 3 the mold is moved with its charge of glass away from the tank and ready for the succeedingblowing operation. The blank mold remains in its inverted position at the second stopping point, and during the period that the mold which succeeds it in the position beneath the tank, is being filled. In going from the second stop to the third stop the blank mold is given a half rotation and this is accomplished by turning the entire mold arm 16 by rotating the gear wheel 12. This is accomplished by means lof the rack 52 which slides in suitable guides on the standard 3, and at its lower end has a roller wrist 53 engaging a. cam way 54 in the tubular stationary standard 2 as plainly shown in Fig. 1, the cam being so constructed that during this movement the rack will be reciprocated, and by its engagement with the gear wheel 12 will give thatwheel a half rotation so as to allow the mold to be in the upright position. The f/blankremains suspended in the upright position at the third stopping point while the ma'- chine is standing still for t-he filling operation of a subsequent mold, and as it moves from the third stop to the fourth stopping point the sections of the blank'mold 28 are opened. This is acomplished by-the camway 33 operating on the roller wrist 32 which, through the connecting rod 31 and the toggles 30 and 29 will operate to cause these sections 28 to open to the position shown in Figs. 4, 5, 6, and 7.

l As soon as the mold arm startsy to travel from the third stoppinO point to the fourth stopping point, the bank molds open as above described and the blowing moldA 41 starts to move upward and during the travel between stops is moved up into the position which the body blank mold held in relation to the blank which position is shown in Figs. 4, 5, 6, and 7. This is accomplished by the following mechanism. The frame 40 has a head 55 which has trunnions 62 at its end journaled in bearings 66, on the brackets 39. Secured to one lendlof one trunnion is a rock arm 57 to which is connected the rod 58 having a roller wrist 59 engaging 1n a camway 60 in the flange 61 secured to the tubular standard 2, the camway 60 being so shaped that at this point in the movement of the standard 3 it will rock the frame from its vertical position shown in Fig. 1 `to a horizontal position shown 1n Fig. 4. During this upward movement the mold sections 41 will remain open until they have arrived at their uppermost position, at which point they are closed by the following means; 63 is a cylinder having a suitable piston (not shown) to which is connected the piston rod 64 which in turn connects to the toggles 65 at the outer ends of which the mold sections 41 are secured. Air under pressure being admitted into the inner end of the piston will operate the toggles `in the outward movement of the piston rod to close the blowing mold section. The air is conveyed to the cylinder by the branch pipe g from the airi supply chamber r which is inside the tubular standard 3 and passes out through an opening 66 in the center of the gear wheel 12, where it branches and one branch connects wit-h the nipple 67 in the end of the trunnion 62 (Fig. 4) which leads through the trunnion to the ports 80 and 82. The other branch connects with the nipple p as above stated. Port 80 connects with the pipe 81 leadingto the inner end of the cylinder. This pipe connection is not shown throughout as it would interfere with the illustration of the other parts, but it is obvious I believe, from this description what the pipe connection is, and a portion of thepipe g is shown in dotted lines in Fig. 1 as connected to nipple 67 from the end of the hollow trunnion 62. 70 is av bottom plate for' the blowing mold which is carried on the stem 71 adjustably secured in the bearing 72 by means of a set screw 73 which bearing` is carried at the outer end of the bracket 74 which is in turn secured to the underside of the frame 40, as shown clearly in Fig. 4. As soon as the blowing mold has inclosed the blank, and during this travel last described, and while the operation of changing the molds is occurring,` the plunger e for makin the initial indentation in the blank is withdrawn. This isl accomplished by means of the spring Z and by shutting off the air pressure which enters through the pipe m below the piston d. This is accomplished as already described by means of the cam wheel o and the .cam groove therein operating the rod u and the valve u. As soon as this valve is closed the pressure of the spring will force out the air through a bleed opening 7 5 in the cylinder head as shown in Figs. 2, 5, 6, and 7. TheA next operation is that of expanding the blank in the blowing mold which is accomplished by admitting air through the ports vv and pipe connection c the air passing from that port into the chamber b and beside the pin e as shown by the arrows in Figs. 5 andv 6. The air for this blowing op-V eration is controlled by the valve fw (Fig. 10) which in turn is controlled by the caml wheel :c which is connected to and operates the valve w, the cam in the wheel being so constructed as to open the valve at this point in the operation and admit air under pressure into the pipe c for blowing. The blowing operation continues during the pe-Y riod that the mold arm remains stationary and during a portion of the subsequent travel thereof, and the air is then shut ofl" by a closing of the valve fw which is done by the further movement of the cam wheel a?. The neXt operation is the opening of the neck mold to the position shown in Fig. 7 This is accomplished by the mechanism already described, to-wit, the cam wheel 26 having the c amway 25, the roller wrist 24 engaging therewith the rod 23 and the toggles v22 and 20 respectively. The next movement is the llowering of the blowing mold with the containedv bottle from the horizontal to the vertical position, and this is accomplished by means of the camway 60 in the flange 61 being so shaped as to move the rod 58 upwardly rocking the rock arm 57 which as previously described is connected to the trunnion of the frame 40 and lowers the body mold frame and the body mold with its contained bottle to the ver, tical position', at which time the mold sections 41 are opened. The mold sections 41 are opened by air admitted under pressure to the opposite end of the cylinder 63. This air is supplied from the pipe g and enters through the end of the trunnion 62 and is carried into the cylinder through a port 82 which connects with the pipe 83 leading to the lowerend of the cylinder, the cylinder head being provided at opposite ends with a bleed opening through which thd air may be exhausted. Air being `thus admitted l and to check or, stop its through the pipe 83, through the piston rod, and the toggle levers described, the mold sections 4l are opened and the completed bottle is dropped out.

Motion is transmitted to the shaft 27 carrying the cam wheels '11, Dvand 26 by means of the beveled gear wheel 84, on the shaft 27 with which the beveled pinion 85 meshes. This pinion is on the shaft 86 which is a horizontal shaft, and extends Aaxially through the aperture 66, in the gear wheel l2, and through the corresponding aperture in the tubular standard 3 to the interior of that standard, where it is provided with beveled pinion 87, meshing with the beveled gear wheel 88 on the vertical shaft 89 which at its lower end has the beveled wheel\90 meshing in turn with the beveled inion 91 on thehorizontal shaft 92 which 1s suitably geared to the shaft 93 by means of the gear wheels 94 and 95. The upper end of the shaft 93 is provided with the worm wheel 9 which is driven by the worm 10 as previously described.

It will be seen from this description-that glass flowing out from the tank or pot may flow in a continuous stream and that I may make bottles automatically and continuously from such flowing means.

O f course it is obvious that instead of having the glass flow continuously the operator can rock the tank or pot 44 to make the glass flow into the mold while it is stationary flow between opera.- tions by a very slighttipping of the tank but this would -require an operator which is.not necessary if the flow is set to give the desired quantity.

I have referred to the body portion of the blank'mold as the body blank mold but it is obvious that the so-called neck mold and the body blank mold together form a mold for forming a blank. If this mold is the shape of the linished article so that no further operation is required the entire article may be finished blank mold.
